Classic Cobra Control Cable Kit Instructions

by Tom Holtey © TopKayaker GeoOdyssey 2018 www.topkayaker.com

These instructions are for the Classic Cobra Control Cable Kit, please print or view this page as your instructions for this kit. It applies to older Cobra brand kayaks; Cobra Tourer (not most recent versions), Eliminator and Expedition, circa 1990s and some years into the 21^st century. May also apply to other Cobra kayaks or custom rudder jobs. Read below and use links in blue text below to see what some of the items that I am referring to look like.

Kit Contents:

B = 8 feet Bungee Cord

A = 4 Bungee Cord Hooks

F = 20 feet Utility Cord, 1/8 in.

C = 6 feet 3/4 In. Webbing Strap

D = 2 3/4 inch Super Locks

E = 2 3/4 in.Tri Glides

Probably more than enough, but gives options for multiple configuration patterns discussed below.

Tools Needed: Sharp Scissors, Heat Source (lighter, candle, torch), Screw Driver or Hex Tool, Wrench.

You may need a Rivet Tool.
If needed you can use stainless steel Self Tapping Screws. A dab of Sealant can be used whenever you apply a fitting.

Cobra Rudder Control Cables Install Process: Secure the bungee cord(s) to tension the foot peddles, from one or two Strap Eyes located forward on the deck, to each foot pedal. Use knots or hooks as desired. You can configure this in any way you like. See the photo of the green Tourer below for V pattern, the white Expedition at top for long side pattern and the blue Eliminator to right for short side pattern as examples. Cobra has configured factory rudders in all three of these styles over the years. You might do this in a temporary manner that will allow you re-adjust as needed.

Trim the bungee cord and gently melt ends with a flame. Overhand knots may be simpler and stronger than the Bungee Cord Hooks.

The bungee hooks are easy to use however, slip the collar on the bungee first, insert bungee into hook base, slide collar onto hook base to engage the teeth. I find that channel lock pliers help me with this.

You will next assemble your adjustment straps using 3/4 Inch Web Strap Products. You will trim the strap, melt screw holes, connect the super locks and finish ends with tri-glides. See strap related videos below. Fasten a super lock to each foot pedal, to the outboard edge, with a very short section of web strap doubled over into a loop and screwed to each foot pedal. Two longer sections of strap will be threaded through each super lock. The length should allow for the tallest and shortest paddlers to reposition the foot control cross bar. Finish each strap with a tri-glide to make a small web strap loop on the end. This loop will be used to tie the cordage to with and Over Hand Knot Loop.

Related Strap Videos (ignore the hatch stuff, all principles of working with strap is the same):

Pro Hatch Repair Part 2 of 3 Cutting and sealing strap ends and melting screw holes.

Pro Hatch Repair Part 3 of 3 Working with tri-glides and buckles (applicable to super locks).

Arrange the foot control cords down the right and left sides of the kayak. Slip the end of the foot control cords through the guides as seen on the gunwales in the photo of the green Cobra Tourer Cockpit above. While the guides above are white, they are most often black and located directly next to strap eyes. The path of the control cables, from the feet to the rudder, should be fairly straight without any sharp turns. Strap Eyes can be substituted as guides if needed.

Fasten cords to the wings of the rudder and to the loops on the aft end of the foot control straps. Use metal or plastic Rudder Shackles (if supplied) or tie directly to the wings of the rudder. Shackles are not needed for adjustment straps. See the Cobra Rudder Knot diagram below. Or… You can tie any kind of knot you like. A bowline knot or tight over hand loop knot should do well. Adjust and trim as needed.

Finally test the rudder system on dry land. Sit in the kayak to locate the foot brace bars (reposition as needed) and adjust the foot control straps to custom fit your leg length. The pedals should be tipped slightly aft. Make sure the rudder turns right and left smoothly by using the foot controls. Re-adjust as needed. Be careful about trimming any cords or strap until you have tested. Try to assemble in a temporary manner, until you are quite confident about the final assembly.

When the dry run test is done you are ready for a water trial. Test the kayak on the water, close to shore in calm weather, before you go and depend on the rudder system in more challenging conditions. When you have proven it is fully functional you are ready for all normal kayak conditions.

Restoration of Classic Dagger Kayak Seats

by Tom Holtey, copyright TopKayaker GeoOdyssey 2019

The seats of older Dagger kayaks can be easily fixed up. While these instructions will largely address Dagger recreational kayaks such as the Blackwater and Zydeco as well as the Bayou and Delta, this will also address many Dagger sea touring kayaks, such as the Vesper and Seeker, indeed any Dagger kayak with a plastic molded textured seat surface (hills and valleys, see photos below).

This page will address old style fabric seat covers that fall apart when they
age. It is assumed that your underlying plastic seat structure, molded as part of the hull (left), or a separate seat structure (right) secured into the hull, is still sound and in good shape.

The original Dagger seat pads for these older kayaks are no longer available from Dagger. Some Dagger kayaks had a one piece seat cover (top photo); others had separate back and bottom pads (use links to left). TopKayaker stocks a generic seat pad set that is compatible with all these older Dagger rec kayaks (top left photo), as well as many Dagger touring kayaks (top right photo and bottom photo). We offer a variety of compatible Seat Pads in our www.topkayaker.com online shop. These instructions will address those seat pads that we have the best success with.

 The first step is to secure the seat strap. Your original seat back cover is probably integrated with the seat adjustment strap in some fashion, probably through “belt loops” on the rear side (see photo to left). It is crucial that the seat strap be secured well to the seat back structure. The old slip-on seat back cover performed this function. It will be fairly easy to re-mount the seat strap. You can re-use the original seat strap if possible (photo to right). Some seat backs had slots on the aft side. If so you can use these slots to secure the seat strap and ignore the next steps.

You will need the 1 in. Footmans Loops, 2 pack. I suggest that you get your stainless steel screws and locking nuts at your local Hardware store. Use the shortest possible screws. Use pointed self tapping screws only for hollow molded seat structures. If you need to replace the seat strap you can use 1 Inch Web Strap Products or the Seat Strap Kit. (Contact us about working with webbing.)
 
Once you have the seat strap secured to the seat back support, the kayak is essentially functional again, ready to use as is. Bear in mind that in the early days of kayaking we did not have any seat pads. Now with the strap secured the seat is ready to apply new padded covers to it.

The Seat Back Pad that we have been having success with for these older Dagger kayaks is the Tour Backrest Pad. It is a strap-on seat back pad. See photos left and right. The Seat Bottom cushion that we have been having success with for these older Dagger kayaks is the Tour Seat Bottom Pad. It is also a strap-on seat pad. See photo below for the finished result.

This Tour Seat Pad Set is a long proven fix for older Dagger brand kayaks.

There are other Seat Pad options and Kayak Comfort Enhancements, such as the Kayak Over-Seat, and the YakPads Paddle Saddle Seat, but the Tour Set above is tested, the most popular and most successful for the majority of older Dagger recreational kayaks and many Dagger sea touring kayaks, all with a textured seat surface (hills and valleys), circa 1990s, up to about 2005.

Self-adhesive pads are not recommended for these textured seat structures. A self-adhesive pad will bridge the valleys leaving gaps underneath that will cause the pad to eventually split down those lines as well as collect dirt, debris, water, and other icky stuff like spiders and ant nests. Such an application may even peel off prematurely.

Some Dagger sea touring kayaks have a seat bottom structure, with a smooth surface, that has a single valley down the center line, as seen in the photo to the left. A self-adhesive pad, such as the Techlift Seat Pad, might be applied after being cut in half down the center line. A thinner pad, about one quarter of in inch might be needed for very tight fitting sea kayaks. The New Town Back Pad can be used as a self-adhesive back pad on the smooth back support surface. Self-Adhesive Close Cell Foam can be applied to any smooth surface seat back or bottom. The advantage of self-adhesive pads is that they stay put during a wet exit, a great benefit to those who practice sea kayak skills.

Some Dagger sea kayaks, and/or white water kayaks may be outfitted with a textured seat bottom structure and a textured back support, maybe a back band. A Back Band (not fully addressed on this page) can be used to replace the original back support.

Modern Dagger kayaks will be much different. Use these links to Dagger Zone Seating Components, as well as other Dagger White Water, Touring and Rec Outfitting items.

Smart Track Foot and Toe Pedal Update

Smart Track introduced new style foot and toe pedals late in 2014 for the 2015 season. These are found on the Performance Toe Pilot FootControls, the Recreational Toe Pilot Foot Controls, the Performance Foot Braces and the Recreational Foot Braces.

The original foot pedals and toe pedals have a rounded face. See photo below.

The new and improved pedal and toe pilot design have a flat face, and offer increased foot contact area, increase turning efficiency up to 25%. See photo below.

The toe pilot springs also changed with the new pedal design.

The old and new pedals and toe pilots are NOT interchangeable. This means an older, rounded toe pilot parts may not be upgraded or replaced with the newer, flatter pedal parts, and vise versa.

This information is applicable to those who are seeking to upgrade Foot Braces into Toe Pilot Foot Controls, or those who seeking replacement parts for the older foot pedals and toe pedals with a rounded face.

Those who are seeking to upgrade a Feel Free Lure kayak with foot controls for a rudder will want the original Toe Pedal Kits with a rounded face.

The TopKayaker Shop will continue to stock the original Toe Pedal Kits with a rounded face as the Original Toe Pedal Kit (With Cables) for rudder upgrade and the Original Toe Pedal Kit (No Cables) best for replacement parts. These Original Toe Pedal Kits will be the best source for small replacement parts compatible with rounded face Smart Track Foot Controls.

The TopKayaker Shop will be stocking new version Toe Pedal Kits with a flat face as the Performance Toe Pedal Kit (With Cables), for rudder upgrade, and the Recreational Toe Pedal Kit (No Cables), also for rudder upgrade. These new version Toe Pedal Kits will be the best source for small replacement parts compatible with flat face Smart Track Foot Controls.

The TopKayaker Shop will be stocking the Performance Toe Pilot FootControls, the Recreational Toe Pilot Foot Controls, the Performance Foot Braces and the Recreational Foot Braces, ALL in the new and improved pedal design with the flatter face (unless otherwise specified in the product descriptions).

Greetings Kayakers!

This blog will serve as a platform to publish information of interests to all kayakers. While the www.TopKayaker.net free online magazine is ending its journey you can look here to see new information. I will be referring to many of the TopKayaker articles, so consider it your "freshman text book".

What has peaked my interest greatly is the restoration of classic kayaks and this will be a primary focus here (as well as parts ID service for more modern kayaks). Fiberglass, composite and plastic kayak hulls are nearly indestructible. These hulls will nearly last forever. The "soft parts" and other fittings will not. Your great grandchildren will inherit that old kayak in your garage. Lord knows, what they will use for a seat, hatch cover or rudder, maybe their cows will be drinking water from the hull. In any case, these old kayaks will be passed down, sold at yard sales and distributed to those who want to paddle them. These classic kayaks can be restored to full working condition, to be used safely for their original intended purpose. These kayaks were good enough for us a decade or two ago, they will be again with some TLC and a little elbow grease.

Yes, there are some kayaks that are lost cause and should be recycled or repurposed, never to paddle again. The reason for such could be many and varied. This topic will addressed at a later date. For the most part, if you have a viable hull, most of the original parts, a budget, some time and effort, as well as some ability to work with your hands, restoring an old kayak could be as much fun as paddling it.

Much of what you will initially see here on this blog will be information on kayak repair, maintenance, and access to parts. In the past decade or so my work at www.TopKayaker.com (the TopKayaker online store) has allowed me to help all kinds of kayakers, customize and improve their kayaks, repair kayaks, obtain hard to find kayak parts and to restore older kayaks back into full working order. So I will be pointing your attention to the TopKayaker Shop often. I like to say that "We have every thing but the hull".

I will not be encouraging people to "Mickey Mouse" or jury rig their kayaks back onto the water. While their might be a little McGyvering and some garage engineering, I will be advising repairs that take into account safety and practical needs within the realm of kayaking. Kayaking as a discipline has many levels in terms of the equipment used and the skills needed, not only to have fun but also to be safe. By percentage most paddlers simply want to float around on a pond, small lake or slow river, their goals and needs are simple, their exposure to risk is minimal. Other paddlers are more serious, even pro level, with more complex goals and greater exposure to risk. While paddling skills cannot be taught completely in a blog, I can address the equipment restoration based on the type of kayak and the intended use of the kayak by the kayak's designer and manufacture. In other words I will not be advising on how to strap a lawn chair into kayak, nor how to convert a white water kayak into a sea kayak, or vise versa. I will also drag my heels on the application of any motor, no matter how small, or designed in the boat from the beginning. I will apply my 38+ years of experience as a paddler, in the paddle sports business, and my common sense, to all that is published here. My goal is to help you restore your kayak back to safe operating condition.

I hope to address some other issues of interest to kayakers here as well, such as destinations, kayak news, reviews of equipment and the history of modern sport kayaking in the USA.

I look forward to our journey together, Tom Holtey

Perception Vizcaya Restoration

The Perception Vizcaya solo touring kayak was produced 1999 through 2002. It was outfitted with the “ComfortTech” foam rubber seat mounted to a seat cradle that is molded as part of the hull. It was also outfitted with an optional rudder system that featured a rather unique rudder assembly. While there is nothing initially wrong with these two features these parts are no longer available.

The Vizcaya is a somewhat rare kayak, not that many were produced. While the Vizcaya is part of the vast Perception “family of kayaks”, its closest “younger siblings” are the Caretta tandem as well as the Napali sit-on-top solo and Mandalay sit-on-top tandem. All had the same unique rudder assembly, only the Vizcaya had the unique “Comfort Tech” foam seat. These features were discontinued when the kayaks were discontinued.

Rudder Replacement (or new rudder installation): 

The rudder assembly for the Vizcaya and its closest “siblings” can only be addressed by means of the SmartTrack rudder system. The key item is the Performance Blade Housing, Rear Mount to be used with the Foil Blade, Solo. (Or the Foil Blade, Tandem if applied to the two tandem kayaks mentioned above.) These Smart Track parts can be used to replace, or add a rudder to a kayak that has not had one before. The first link in this paragraph will lead to some basic info on the system. 

The original Perception Keepers Foot Controls and cables are compatible with the SmartTrack rudder assembly and are still available; to replace old, or add to a kayak that has not had them. Use the first link in this paragraph as well as the TopKayaker indexes to All Skills and Customization to learn more about rudder system installation and repair. Contact me as needed. FYI: I do not typically recommend Smart Track Toe Pilot Foot Controls (recreational or regular) for use with sit-on-tops, but it can be done with the rec version. 

Perception Vizcaya Seat Replacement: 

Important! The NeckyTouring Seat Pad Kit, described below, has been discontinued and is now sold out. The staff at TopKayaker is currently seeking a substitution. The results will be published here. The Necky seat info is left here for archival purpose.

It would be possible to carve some Close Cell Foam as a seat bottom cushion. Please Contact Tom for more info or to report your results.

The original seat for the Perception Vizcaya is no longer available as a replacement part. These seats will typically rot like an old foam rubber toy. The seat should be replaceable with modern components that are currently available. It will be a custom job requiring a bit of tinkering on your part. 

You will want to completely remove the old foam rubber seat and seat strap. Take steps not to damage the seat frame under it. It is not advisable to remove the seat frame. It is molded as part of the hull and may play a structural role. 

The Vizcaya is 24 inches wide, at the beam, with a cockpit coaming that is published to be 21 inches wide. The space from one side of your seat frame is about 18-20 inches to the other side. It was possible to use the discontinued the NeckyTouring Seat Pad Kit (commonly found in modern Necky sea kayaks about 22 inches wide). The seat pad at the link above was used in modern Necky brand kayaks with a similar, but different, frame (Necky Seat Frame) that you would not need. The Necky Touring Seat Pad Kit came with Velcro adhesive strips and some push rivets. This may or may not be completely adequate to the secure the Necky seat well to the existing Viscaya seat frame. Some additional Velcro, maybe some adhesive and possibly some screws and nuts for the seat pad “ears” might be needed. It is also possible that you may need to elevate the seat with a slab of Close Cell Foam. 

Currently we are suggesting the Kajak Sport Ergo Seat as a possible option for the Vizcaya. Check the dimensions of your seat frame, side to side and select the Ergo seat size that will fit the space allotted. Mount the Ergo seat to the seat frame with two to four stainless steel bolts, washers and lock-nuts, horizontally through the seat posts (looks like arms on an armchair). This has not yet been tested. Please Contact Tom for more info or to report your results.

You will want some back support too. For the most part you can select any of the sea kayak style BackBands. Back Bands are generic, and all are more or less the same for comfort. I will suggest two options below:

The Kajak Sport Back Hi Profile Back Band or the Kajak Sport Back Lo Profile Back Band are best used with the Ergo Seat. Use this link for info on how-to install: Kajak Sport Back Band Instructions
The Seals options below would be best for any type of foam rubber seat:

 

Seals Back Band, Small Dimensions 14 inches by 5 1.4 inches

Seals Back Band, Large Dimensions 15 inches by 6 1/8 inches

Use the link below for more info on how-to install: Seals Backband How-To Video

Get the Small (Lo-Profile) if you are a small or medium person, or you feel that it will fit your back or the kayak better. Get the large (Hi-Profile) if there is lots of room in the cockpit, or you are a large or tall person (maybe medium too) or you have a clear need for extra back support ("bad back").

Back Bands with a lower rear anchor strap cannot easily be used on a foam rubber seat, but an extension of the rear lower strap might be applied to the middle of the seat frame, under the seat pad.

One would want to "test sit" any seat retrofit (on dry land) and then test paddle the kayak (in clam water close to shore) with the seat temporally installed the cockpit. Assess the need for elevation with close cell foam. Consider adjustment fore and aft as needed. Bear in mind that adhesives and push rivets will be difficult to take apart if you need to re-do. Try to make your plan such that it can be re-configured, just in case you need to make a change. 

Now that you have the basic seat components in place, and have test paddled, you can fine tune the plan with some Close Cell Foam bottom paddling and/or other Hardware bits, if needed.

Next test paddle the kayak in a "sea trial", not too adventurous, with a bailout plan, just in case your install is not working to you satisfaction. When your kayak, with its new seat, has proven itself you can them use it fully as it as the sea kayak it was intended to be. 

Assuming you are going to be paddling this kayak as a sea kayak, or as a fresh water touring kayak (big lakes), probably wearing a Spray Skirt and possibly practicing some sea kayak skills, some hip pads might be something to think about. The Harmony Hip Pad Kit (or other hip pad kits) would be advisable as the next custom outfitting. 

You may have other questions about restoring the Vizcaya. Feel free to contact me. You might try this retrofit on your Vizcaya. Please feel free to share your results with me. 

(Photos below show before images. Send me your after images and I will post them.)

Happy Paddling, Tom Holtey,
